Rodin's Thinker is introverted. Here these thinkers ponder the apparent chaos of the world in order to extract from it the universal truths and principles that can be counted on. These principles, once extracted, will provide the logical structure on which to build strategies.

They have a finely nuanced ability to analyse situations, find root causes and foresee consequences. They distrust action taken too quickly without the necessary investigation. They are usually levelheaded, objective, impersonal yet intensely involved in problem solving. They are fiercely independent, seeking input and comments from a chosen few. When reporting to others, they need to establish credibility first: their own and that of the person they are reporting to. If the gap in knowledge and expertise is too great and their own proficiency dismissed, belittled or ignored, they will lose interest and motivation.

They are less interested in running the world as they are in understanding it. They are curious and capable of explaining complex political, economic or technological problems, taking great pleasure in explaining all the factors and intricacies. They are rigorous with their thoughts and analysis, choosing the exact words that convey precisely what is meant. They may spend a lot of time defining words, concepts and systems in order to define a problematic solution.

They are armchair detectives, scientists and philosophers, spending most of their time in quiet reflection to ponder truth, and solve mysteries. They may tend to neglect social requirements and responsibilities, finding many relationships to be too superficial to be of much interest.

INTPs are pensive, analytical folks. They may venture so deeply into thought as to seem detached, and often actually are oblivious to the world around them.

Precise about their descriptions, INTPs will often correct others (or be sorely tempted to) if the shade of meaning is a bit off. While annoying to the less concise, this fine discrimination ability gives INTPs so inclined a natural advantage as, for example, grammarians and linguists.

INTPs are relatively easy-going and amenable to almost anything until their principles are violated, about which they may become outspoken and inflexible. They prefer to return, however, to a reserved albeit benign ambiance, not wishing to make spectacles of themselves.

A major concern for INTPs is the haunting sense of impending failure. They spend considerable time second-guessing themselves. The open-endedness (from Perceiving) conjoined with the need for competence (NT) is expressed in a sense that one's conclusion may well be met by an equally plausible alternative solution, and that, after all, one may very well have overlooked some critical bit of data. An INTP arguing a point may very well be trying to convince himself as much as his opposition. In this way INTPs are markedly different from INTJs, who are much more confident in their competence and willing to act on their convictions.

Mathematics is a system where many INTPs love to play, similarly languages, computer systems--potentially any complex system. INTPs thrive on systems. Understanding, exploring, mastering, and manipulating systems can overtake the INTP's conscious thought. This fascination for logical wholes and their inner workings is often expressed in a detachment from the environment, a concentration where time is forgotten and extraneous stimuli are held at bay. Accomplishing a task or goal with this knowledge is secondary.

INTPs and Logic -- One of the tipoffs that a person is an INTP is her obsession with logical correctness. Errors are not often due to poor logic -- apparent faux pas in reasoning are usually a result of overlooking details or of incorrect context.

Games NTs seem to especially enjoy include Risk, Bridge, Stratego, Chess, Go, and word games of all sorts. (I have an ENTP friend that loves Boggle and its variations. We've been known to sit in public places and pick a word off a menu or mayonnaise jar to see who can make the most words from its letters on a napkin in two minutes.) The INTP mailing list has enjoyed a round of Metaphore, virtual volleyball, and a few 'finish the series' brain teasers.

INTPs in the main are not clannish. The INTP mailing list, with a readership now in triple figures, was in its incipience fraught with all the difficulties of the Panama canal: we had trouble deciding on:

1) whether or not there should be such a group,

2) exactly what such a group should be called, and

3) which of us would have to take the responsibility for organization and maintenance of the aforesaid group/club/whatever.
